Objective To investigate the effects of clearing meibomian gland ducts prior to cataract surgery on the gland dysfunction and dry eye induced by surgery. Methods A prospective, randomized controlled trial was conducted on 110 patients (110 eyes) undergoing elective cataract surgery for senile cataract in our department from June 1, to December 31, 2021. The participants were randomly allocated into treatment (n=56) and control (n=54) groups. The patients from the treatment group were given eyelid compresses and cleaning to remove an obstructed meibum in 1 week prior to cataract surgery, while those from the control group received no such treatment. Ocular surface disease index (OSDI), indicators related to meibomian gland function, including tear film lipid layer thickness (LLT), meibomian glands yielding liquid secretion (MGYLS), meibomian glands yielding secretion score (MGYSS), and tear film break-up time (TBUT) before, and 1 and 3 months after surgery were employed to evaluate the efficacy of clearing meibomian gland ducts. Results The control group exhibited significantly decreased MGYLS (P

Objective To compare the surgical efficiency and postoperative evaluation indicators between active-fluidic pressure control phacoemulsification system and gravity-fluidics in dense nuclear cataract surgery. Methods A total of 60 patients (60 eyes) with age-related cataract admitted in the First Affiliated Hospital of Army Medical University from January 2020 to December 2020 were enrolled in this prospective study, and all of them were classified as NⅣ grade according to the Lens Opacities Classification System Ⅱ (LOCS Ⅱ). They were randomized into the active-fluidics group (n=30, phacoemulsification by active-fluidic pressure control system) or the gravity-fluidics group (n=30, phacoemulsification by gravity-fluidic system). Intraoperative parameters, such as cumulative dissipated energy (CDE), ultrasound total time (UTT), torsional amplitude (TA), torsion usage time (TUT), aspiration time (AT), and fluid used (FU) were recorded and compared between the 2 groups. Postoperative evaluation indicators, like central corneal thickness (CCT), central corneal edema and thickness (CCT) at 1 d after surgery were also collected and compared. Results There were no significant differences in preoperative best corrected distance visual acuity, CCT, and corneal endothelial cell count between the 2 groups. Intraoperatively, the active-fluidics group had significantly lower CDE, UTT, TUT, AT and FU than the gravity-fluidics group (P < 0.05), though TA did not differ. Moreover, the active-fluidics group also presented better UDVA (P=0.005), less increase of CCT (P=0.006), slighter central corneal edema (P < 0.001), and smaller proportion of patients with moderate to severe central corneal edema (P < 0.001) than the gravity-fluidics group in 1 d after surgery. Conclusion The active-fluidics configuration achieves a higher surgical efficiency than the traditional gravity-fluidics system in phacoemulsification of dense nuclear cataract, with slighter postoperative corneal edema, less change of CCT and faster recovery of UDVA.

ObjectiveTo compare the intraoperative efficacies of active-fluidic pressure control phacoemulsification system versus gravity-fluidics on intraoperative efficiency for primary angle-closure glaucoma with cataract, and investigate their effects on postoperative central corneal thickness(CCT), intraocular pressure(IOP), and count of corneal endothelial cells. MethodsA total of 24 patients(48 eyes) with primary angle-closure glaucoma and also accompanied with cataract undergoing surgical treatment in our ophthalmology department from June 2016 to December 2019 were prospectively recruited in this study. With the aid of Alcon Centurion Phacoemulsification Vision System, these patients underwent phacoemulsification with active-fluidics configuration in one eye(active group), and with gravity-fluidics configuration in another eye(gravity group). Their intraoperative parameters, such as cumulative dissipated energy(CDE), total ultrasound(US) time, torsion use time, torsion amplitude, aspiration time, and fluid use, were noted and compared between configurations. Endothelial cell loss, and CCT and IOP changes were evaluated at 1 d, 1 week, and 1 month postoperatively. ResultsThere were no significant differences in the baseline data between the 2 groups. The active group had significantly shorter total US time, torsion use time and aspiration time, and lower amount of fluid use than the gravity group(P

Objective: To assess the clinical value of single-port video-assisted thoracoscopic surgery (VATS) for treatment of pulmonary diseases., Methods: From October, 2009 to December, 2013, 105 patients with pulmonary diseases were scheduled for single-pore VATS for pulmonary lobectomy (19 patients), wedge resection of the lung (34 patients), and bullae resection and pleurodesis for spontaneous pneumothorax or pulmonary bleb (52 patients)., Results: Of the 105 patients, 101 patients underwent single-port VATS; the procedure was converted to open thoracotomy in 1 patient and to conventional three-port VATS in 2 patients. The operative time was 50.6∓36.8 min (20-200 min) with intraoperative blood loss of 70∓56.9 ml (10-300 ml), thoracic drainage time of 4.2∓3.2 days (2-14 days), and postoperative hospital stay of 5.4∓3.8 days (3-16 days). Postoperative complications of the procedures included prolonged air leakage (6 cases) and atelectasis (2 cases). All the other patients recovered smoothly without serious complications., Conclusion: Single-port VATS is a safe and efficient procedure that allows rapid postoperative recovery and is a method of choice for selected patients with pulmonary diseases.
